For those of you who don't know what google cardboard is, it's Virtual Reality for Android in which you use a cardboard (or in some cases, plastic) headset that you put your phone in.
There will eventually be a settings menu for a girly/jungle environment, change of music (for now it's just Greensleeves for discretion purposes), changing the length of the nap (it automatically quits in 30 minutes for now), and changing what the mobile looks like.
It's still a WIP. It also will not be on the play store- I'm going to privately host it on google drive.
